Im 232 lbs and stock gearing on my 2020 CRF250L at 14/40 was too tall and barely pulled 6th gear well at all.. 13/42 was too low and felt like engine was winding at 6500 rpm at like 55/60. 14/42 seems perfect to me and have installed speedometer corrector to fix the approx. 5mph variance at 50mph.. thanks for the video!
I use 14/48 on my CRf250L which was recommended to me by many more experienced riders. Works well for off-road. Pulls really well in lower rpms and can usually start from and stay in 2nd gear for most hills.
@@ZacharyUlrick Yes, also had to change the chain. Didn't do it myself though, I live in Thailand where labor is very cheap or usually the shop you buy from installs for free. I went there with pretty much a stock CRF, had them change exhaust, tires, tail tidy, handlebar, grips, sprocket, chain, hand guards and suspension. Free installation, only paid for parts. Enjoy watching your videos, those are some very nice trails you have in Southern California!
14/48 Setup (Standard): With a final drive ratio of 3.428, this setup provides a balanced performance ideal for mixed on-road and off-road use. Top speeds reach 102 km/h in 6th gear, making it the fastest of the three setups. It retains sufficient low-end torque for trail riding while allowing comfortable cruising on highways. This configuration is optimal for riders seeking versatility and efficiency across varied terrains. 14/51 Setup (Trail-Oriented): The 14/51 setup increases the final drive ratio to 3.643, enhancing torque at the cost of reduced top speed, which maxes out at 96 km/h in 6th gear. It delivers improved control and climbing ability, making it suitable for technical trails or steep gradients. The higher torque output ensures better traction and acceleration in challenging off-road conditions while maintaining reasonable road capability. 14/53 Setup (Torque-Focused): The most torque-oriented option, the 14/53 setup, with a final drive ratio of 3.786, prioritizes power delivery over speed. Top speed drops to 92 km/h in 6th gear, but the increased torque provides excellent low-speed control for rugged terrain and heavy hauling. This setup is perfect for extreme off-road adventures or technical riding where maximum pulling power is required.
I think that could be great based on my experience. The supermoto setup will give you more speed and stability on the road for sure. All you can really do is it try it out and see how it goes. I know it's not a cheap experiment, but I think you'll be happy with that setup!
For just faster highway speed, leave rear sprocket at 40 and put on larger front sprocket if you can find one. 15 or 16 tooth. But honestly, I wouldn’t do this. You won’t be happy with the low end performance. Remember everything is a trade-off
I like the stock gearing for the road I don’t think it could get any better but when I run Trail I actually run a 48 tooth on the rear It’s a pain in the ass to switch them but if I don’t I don’t enjoy the ride
good content but that background music is creepy. 14/44 from stock 14/40 works for me. I dont like reducing the countershaft sprocket (front) because it adds too much slop to the area where the chain feeds through at times when the chain is slack. That chain beats up the case. So, I only make changes to the rear sprocket.
I did replace the chain. You should always replace the chain when replacing the sprockets so that you get even wear patterns. I replaced it with the D.I.D. 520 VX3 Gold X-Ring 120 Link Chain
i was about to put a 42t rear (14t front)but not sur if i ´ll see big improvement on Trail, maybe should i Go with 44 just like you..i just not want loose too much speed on roads.Thanks for your video!
There is always a give and take with gearing. You will notice a difference on the highway. I actually ran the 14/42 for a few hundred miles. I liked it but not quite as good as the 14/44. I'm happy with this gearing and I can keep up with traffic at 55 to 60 mph no problem
Stock front, 44 rear is great if your roads aren’t above 60MPH. 3rd on fire roads and 2nd on hill climbs. Best mod out there ( over mufflers and fuel controllers IMO). I’ve been on my 250L since 2015.

Same here 14/48 is awesome I thought if too big I can always swap 14/44
I have a 2017 CRF250L, FMF, EJK running 13/44, it seems flat in 2nd gear in the sand/hills so I just ordered a 48T rear. Hope to give it more umph....

nice! Did you have to remove the black plastic feeder from the chain guide on the swingarm?

That's really cool! Free Installation is unheard of here. I do the work myself. Glad you liked the videos!
Just did 14/48 myself coming from 13/42. Perfect for my needs, 90% dirt.

I converted it to supermoto, how will it be 14/38? I wonder if the rims are 17 ich.??

Im doing 13/40 on mine and its damn near the same as the 14/42. just a tiny bit more umph in the low end
What to do for increasing top speed at highway? Thanks for video
From what I have seen they don't make a rear sprocket smaller than 40T. If you can find a smaller rear sprocket, that would do it.
For just faster highway speed, leave rear sprocket at 40 and put on larger front sprocket if you can find one. 15 or 16 tooth. But honestly, I wouldn’t do this. You won’t be happy with the low end performance. Remember everything is a trade-off
@@jkabee that's very true. However, I think the chain might not fit in the front sprocket housing with a bigger sprocket. Thanks for the comment
Buy a sport bike
@@ZacharyUlrick very good point. I didn’t consider that!
I like the stock gearing for the road I don’t think it could get any better but when I run Trail I actually run a 48 tooth on the rear

Run a 14/51 tried 42/45 /50 off-road great for blips
That is a clean looking chain! The extra push may get you over that hill.
I hope so!
mine is 13/52
How did it go?
What size and brand of back tire is on your bike?
Its 120/90-18 Dunlop D606
Hey bro what tube sizes do you run for your d606?
@@SoMissingFive0 120/80-18 and 3.00-21

Yeah, not sure why I did the music! Lol.
How many rear gears should be needed to make a single wheel on a CRF 250?
which model it is the 42?? link to purchase please! 🙏🏼😊
It was a renthal. I think I got it on CRFs only. It's been a while
good video💪
Thanks
What did u change on your rear tire?
I have been using the Dunlop D606 for quite some time and I have no complaints. It's a great tire!
Do you needed to change the chain? And if yes what size? Thank you
I did replace the chain. You should always replace the chain when replacing the sprockets so that you get even wear patterns. I replaced it with the D.I.D. 520 VX3 Gold X-Ring 120 Link Chain
@@ZacharyUlrick Thank you
Did you have any issues with your ABS after you changed gearing?
Nope, no issues
Thanks. I had heard if you change gearing on an ABS bike you would get an error light on the ABS system.
@@stephenrozek5440 not for me. I've changed it twice.
ABS is completely independent of the chain/sprocket. There should be no error code. Perhaps changing wheel/tire size did this?
Whats your top speed with 14-44
I think it was about 70 comfortably. Could do more but not without over revving.
What’s the rear tire???
Dunlop D606
Im getting one thats 13/45

That may have been the most boring video that took way to long to watch to find out nothing.
